  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

1. Way to know everything is alright with the breeding male






2. Duct through penis that carries sperm and urine






3. Animal which has been castrated after puberty






4. Not being bred back into herd. horses are seasonal breeders vs. cows as anytime breeders






5. (switzerland) 2nd in size and milk production - most muscle -






6. BST given to dairy cattle makes the mammary gland more persistent - helps produce more milk. good as Long-term because it does not cause cow to bulk up - provides more milk/cow Which means less cows needed - less cows need to be given feed - lower co






7. Scar tissue plugs up chambers of udder






8. ~60 days before calving






9. Produce testosterone. located between the seminiferous tubules






10. Boars and stallions-> deliver semen directly into the cervix. bulls and rams-> deliver semen into the vagina.






11. 16-20 hours






12. Pulls sperm and egg together - gets body ready for pregnany - stimulates growth cells - develops mammary glands - starts to deposit fat.






13. 114 days






14. Why Dairy calves are fed powdered milk.






15. So when offspring are born - there is more food to be found for energy stores and fat deposits IN THE SPRING






16. Implies the amount of estrogen production






17. Front feet and head first. (except for hogs and dogs)






18. 114 days






19. 14-19 (17) days






20. Boars and stallions-> deliver semen directly into the cervix. bulls and rams-> deliver semen into the vagina.






21. When are steers and heifers weaned from bottle feeding?






22. Hold the penis in the bulls body when not in use. releases penis before ejaculation or urination.






23. Contains and regulates the temp of the testes for sperm production






24. Look for infection - split - and rupture of the penis






25. BST given to dairy cattle makes the mammary gland more persistent - helps produce more milk. good as Long-term because it does not cause cow to bulk up - provides more milk/cow Which means less cows needed - less cows need to be given feed - lower co






26. Animal which has been castrated after puberty






27. Microscopic - make sure not sterile - very few bulls are actually tested






28. 1. bring in new genes - 2. replace males with leg problems (difficulty breeding) Note: culling has a much greater emphasis in the dairy industry vs the beef industry.






29. Male on one pin and female on other side






30. Male on one pin and female on other side






31. Depository for semen during insemination. where urine leaves the body






32. 1. seminiferous tubules - 2. sertoli cells - 3. leydid or interstitial cells






33. FEED






34. Located directly in front of the cervix. fertilized egg implants here. connected to two uterine horns. implantation occurs on the same side as ovulation occurred.






35. (male) pushes the testes upward toward the body for warmth or protection






36. Organ of copulation - provides passageway for semen and urine - muscular organ characterized especially by its spongy - erectile tissue that fills with blood






37. (male) definition: duct located outside of the testes. 3 parts: head - body - tail. 4 Functions:concentrate sperm - store sperm - transport sperm - site of sperm maturation. entire process takes ~40-60 days






38. Milk ~305 days - dry 60 days prior to calving






39. (LH) stimulates the Leydig cells to produce testosterone






40. 19-23 (21) days






41. Help to signal hormone levels which we need both in the brain right next to each other.






42. Urinary calculi.






43. So when offspring are born - there is more food to be found for energy stores and fat deposits IN THE SPRING






44. Sperm is produced here






45. Failure to have both testis (gonads) descend






46. Sperm production






47. Located directly in front of the cervix. fertilized egg implants here. connected to two uterine horns. implantation occurs on the same side as ovulation occurred.






48. (switzerland) 2nd in size and milk production - most muscle -






49. (FSH) causes egg to mature in females






50. 1. reproduction - 2. mastitis/udder problems - 3. low milk production - 4. soundness/poor feet and legs (living on concrete)
